The object of this in'ventionis to provide a simple eppsmius whereby the several fertilizer materials may he pro gerly PTOPOY- lioned thoroughly mixed end reduced to the desired fineness-end delivered direct to e. such-er, as more fully hereinafter set forth" ln the drawing" Fig; l is e'plan View of my apparatus;

In .lhc drewings enne 'ed, designeies the imperforute section of the mining-cylinder'und l1 ihe perforated or reticulated or screen section of the cylinder, this cylinder being uiiixed to e supporting shaft 12 by means of e series of spiders l3, oneheing;

end-of the cylindcr, another ut the point Where the imperforole cylinder joins the screen section, and the remaining one at the exil; end of the screen section. The shaft end its cylinder. incline downwardly from the inlet to the" which end of the cylinder, so that the fertilizer inuterielr when delivered into the forward and of 'lhe cylinder nndfihe cylinder is revolved, will gravitate toward the lower, exii: end.

The "fertilizer meizeriels, properly proportioned, are delivered, by gravity, into the upper end of the cylinder by means of chute 14 which projects into inlet-end of the cylinder to as distance short; of the first spi er 13. The extreme upper end of the seclion l0 oi the cylinder, i. e, that por tion which projects shove the said spider 13,

' is curved inwardly at 15 to form e dam which functions to prevent spillings't this inletend oi the cylinder. The fertilizer materials are. mixed and lorolrenup in the iniplerforate section 10 as the cylinder rotaies and the materials are finally delivered onto the screen section 11 which serves not only to further mix and break up the lumps but also to screen our: the materials that have been reduced to u sullicicnis fineness to pass through the screen. lhe screened and mixed meterisls drop into chu'ie 16 whose upper end partly surrounds the screen seclion, and thence through :1 downwardly-in clined ll s, sucker 18 mounted at one side of she frame of the npgieruins. The

Y. chute.

that have come down through the screen. This crusher is driven by means of a belt 21 which in rum is driven by a pulley on the resin drive-shaft 22 extending across the lower end of the machine frame The final spider is provided with an inwardly-exsending annular flange 23 which series as s, dam. for holding the fertilizer materials until. they have been Well jumbled in the screen section of the cylinder, so that only the lumps shall pass over into the crusher.

The cylinder is driven by means of a sprocket-Wheel 2 forming part of the final spider, the sproclre't-chein 25 for this Wheel being driven by a, sprocket-Wheel aiiixed ic e; counter-shah; 26 yournuled on the frame and extending substunhially parallel with the 1?, to be mixed with th'cmaterials screen section of the cylinder, this counlershaft being driven by bevel-Wheels 2'? on the main drive-shaft 22. This counter-shaft 26 is providedv Wich a, pulley 28 which is helical to the convcyonmsmber of the sucker 18 to thereby continuously actuate the sucker mechanism While the sucker is being filled from the spout 17'. y

The inlet-spout 14 is connected with the outlet 29 of shopper 30. This hopper 30 is a large rectangular trough or box open throughout its upper surface. The outlet 29 is formed in the Well of this box their adjacent to'the mixing-cylinder, A. extends across shis hopper or hon one side of the outlet 29 This gate is mounted to slide in vertical ways 32 attached $0 the Walls of the box. A similar set of Ways 32 is arranged at the opposite side of the outlet 29. The purpose of this specially designed hopper is as ilollows: While 'the materials that are in that section oil the box which is in connnuuiculion with the outlet 29 are being raked or shoveled through ihe outlci; 29 into the chute 14-, the fertilizer lllilllellillfi urc being. placed in the othen cu soil section oi lhe hopper in layers, the veri ous materials having); been previously weiqhailer one section of the hop per lius thus been emptied into the mixing-cylinder,

the gate 31 is shifted over to the other ides 32 to thus openup the previously- 'led section, to thereby permit the mate- 'rials placed therein in layers to be shoveled reference to each other over a considerable grinding area, but the process of feeding the mixingcylinder may be continuously carried on.

What I claim as new is: 1. In a. mixing apparatus, a mixing and cylinder mounted on a shaft and having its lower end provided with a cylindrical screen, an external sprocket-wheel on the lower, screen end of the cylinder, a counter-shaft arranged parallel with the cylinder and being provided with a sprocketwheel connected to the sprocket-wheel on the cylinder by a sprocket-chaima sacker driven from this counter-shaft, a receivingchute embracing the screen portion of the cylinder and having a spout for delivering the screened material to the seeker, a lumpgrinder having its hopper positioned to receive the lumps as they fall from the rear, screen end of the cylinder and having its walls, and a gate extendin across the hog per and means whereby t s gate may placed at either side of said exit, for the purposes set forth. v

3. In a fertilizer-mixing apparatus, a

cylinder having an imperforate entrancesection and a screen-section at the delivery end, means for driving the cylinder embodying an external sprocketewheel carried by the cylinder at its delivery-'end, this sprocket-wheel being open and rovided with an annular flange extending inwardly to form a lump-dam, a. lump-grinderhaw ing its hopper positioned to receive the lumps as they roll over said dam at the rear, lower end of the cylinder, a s rocket-chain for driving said cylinder t rough said sprocket-wheel, ,and means for driving said sprocket-chain and also said lump-grinder.

In testimony whereof I hereunto; afiix my signature.
